To Test Compliance with Authority, a classical experiment in Social Psychology requires subjects to administer increasingly painful electric shocks to seemingly help victims who agonize in an adjacent room. Each subject earns a score between 0-30 a score of 0 signifies the subjects unwillingness to comply at the very outset, and a score of 30 signifies the subjects willingness to comply completely with the experimenter's orders

In one condition, shocks are administered only after an affirmative decision by a committee, consisting of one real subject and two associates of the investigator, who act as subjects. In the other condition, shocks are administered after an affirmative decision by a solitary real subject

A total of 12 subjects are randomly assigned, in equal numbers, to the committee condition (X1) and to the solitary commission X2. A compliance score is obtained for each subject. Use t to test the null hypothesis at the .05 level of significance. In addition, please calculate Cohen's d as a measure of effect size .
